Installing a Motorola 56k Modem..ERROR

By cyberghost_1 ·
I tried installing a Motorola 56k Voice/Fax Modem on a XP PRO PC, I get a security warning stating that the DRIVER is NOT Digitally Signed by Microsoft. I choose to continue the install and I get a BLUE screen stating that XP has been shut down due to an avoid damaging the system. On the box for the Modem it says that it is not Signed by MS and when I get the Security Warning, to continue...supposedly without a problem. Obviously there is a problem, since I get the blue screen and XP and the PC has to be restarted. In the help screen for "Why is the Digital Signature Important" It suggests Windows Update...This PC has not been updated that much. Also, XP was currupted once about a month ago, I repaired the installation, since then the PC has been VERY SLOW on startup and opening anything. There is no valuable info on the HDD. Just the basic...XP, Office XP, Works, Nero, Adobe....the basic package. The owner hasn't used it yet...
I think I should format the HDD and reinstall everything...and start from scratch....What is the deal with all this?

You do not need to re-install. Try booting in safe mode and then use device manager to un-install the modem. If that then allows a good boot then it is the modem and you need a new driver set for it.

You did not mention what service pack you have. If it is SP2 then the driver may work with XP, but not SP2.

There are a lot of Motorola 56k Voice/Fax Modems. Is it older, or newer. What model number?

Let us know about deleting it and the other info, and lets see what we can do.

Good Luck,

Judging by what you have said regarding the history of the PC, the fact that you needed to repair the installation, and that since then it has been slow, I would do a complete reinstall.

Even if you do get the modem installed correctly, it may be that there will be another problem later. Cut your losses and do a complete reinstall, especially if the owner has not used it much.

Good luck

It may also be a problem with the brand of chipset on the modem. If you have access to another modem with a different chip set, try that and see if it works. I have had this problem before and keep three different chip set modems on hand.

giving the fact that you had to do a repair to the operating system ,and now running slow and slow to respond , there is obviously something still not quite right with it, I would do a format but i would go one step further and go to the HDD manufacturers site and download a diagnostic utility and and lowlevel format the drive then using the xp cd create and format then reinstall windows then SP2, I have recently revived 2 HDDs just by doing this. Some might say it is over the top but it may just save having to replace the HDD unnecessarily and save some $$.
